Open book in-person text file exam

Overview

You are required to fully describe how to answer the question. You do not have to write code as long as you accurately describe the design of a solution. You must specify which language elements (like bit-wise operators) are used and how they are used.

If you use ONLY code for your answer make sure it is 100% valid code.
